A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI(G)S or CIS cell) is a used to convert sunlight into electric power. It is manufactured by depositing a thin layer of solid solution on glass or plastic backing, along with electrodes on the front and back to collect current. Because the material has a high and st.
